"Write songs about it," said Swift, who penned the tune "Always and Forever" about her split with Jonas. Do guys ever get intimidated by that? "I think they are starting to realize that if they are involved with me in any way, I will probably write a song about them," she added. "You know what, if they don't want me to write bad songs about them, they shouldn't do bad things."

A guy who could do no wrong? Justin Timberlake. He recently surprised Swift on a taping of The Ellen DeGeneres Show.

"I just couldn't believe he was there!" Swift told Us. "He is absolutely my favorite person on the planet. For her to invite Justin Timberlake to come and be there to celebrate my album release week, it just says a lot about who Ellen is and how amazing she is."
